Answer:

y < 3x - 9

Step-by-step explanation:

Given

3x - y > 9 ( subtract 3x from both sides )

- y > - 3x + 9

Multiply through by - 1, reversing the symbol as a result of multiplying by a negative quantity.

y < 3x - 9 ← in slope- intercept form

Find the distance between the two points and simplest rational form (3,-4) (6,-7))
pychu [463]

Answer:

D = 3\sqrt{2}

Step-by-step explanation:

Given

(x_1,y_1) = (3,-4)

(x_2,y_2) = (6,-7)

Required

Determine the distance between the two points

Distance (D) is calculated as:

D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Substitute values for x's and y's

D = \sqrt{(6 - 3)^2 + (-7 - (-4))^2}

D = \sqrt{(6 - 3)^2 + (-7 +4)^2}

D = \sqrt{(3)^2 + (-3)^2}

D = \sqrt{9+9}

D = \sqrt{18}

Express as 9 * 2

D = \sqrt{9*2}

Split:

D = \sqrt{9}*\sqrt{2}

D = 3*\sqrt{2}

D = 3\sqrt{2}

For a project in his Geometry class, Mamadou uses a mirror on the ground to measure the height of his school's football goalpost
andreev551 [17]

Answer:

Height of the goalpost is 9.25 m.

Step-by-step explanation:

As per the rule of reflection in physics,

Angle of incidence = Angle of reflection

As we can see in the picture attached, both the angles (θ) are equal.

m∠ACB = m∠ECD = 90° - θ

m∠ABC = m∠ADC = 90°

Therefore, both the triangles ΔABC and ΔEDC will be similar.

And by the property of similar triangles, their corresponding sides will be proportional.

\frac{AB}{ED}= \frac{CB}{CD}

\frac{1.75}{ED}=\frac{2.6}{13.75}

ED = \frac{1.75\times 13.75}{2.6}

ED = 9.25 m

Height of the goalpost is 9.25 m.

In one day, Annie traveled 5 times The sum of the numbers of hours Brian traveled and two. Together they traveled 20 hours. Find
grigory [225]

5B + B = 20

6B = 20

B = 20 / 6  

= 10/ 3 hrs

A = 5 ( 10/3 + 2)

 = 5 (16/3)

 = 80 / 3 hrs  

 Brian traveled 10/3 hours and Annie traveled 80/3 hours.

Reduce any fractions to lowest terms.Don’t round your answer, and don’t use mixed fractions
DENIUS [597]

Answer:

t < \frac{38}{17}

Step-by-step explanation:

Add '5t' to both sides

12t - 2 +5t < -5t +36 +5t

17t -2 < 36

Add ' 2' to both sides  

17t -2 +2 < 36 + 2

17t < 38

Dividing '17' on both sides

\frac{17t}{17} < \frac{38}{17}
